The disclosed subject matter relates to a solar power supply device for a light, comprising at least one tubular solar module that can be slid onto a mast, and a crown which can be fitted to the top of the mast and from which the solar module is suspended, wherein the solar module contains in its interior at least one pair of spring elements that can be resiliently spread apart, between which the mast can be passed through. The invention further relates to a lighting device comprising a mast and a solar power supply device of this kind, the crown of which is fitted to the top of the mast and through the spread-apart spring elements of which the mast is passed through, and at least one light that is supported by the solar power supply device and is electrically powered thereby.

The disclosed subject matter relates to a solar-operated lighting device comprising a substantially tubular solar module, which is positioned vertically in its mounted position and electrically powers a light via at least one rechargeable battery and an electronics module, the at least one rechargeable battery and the electronics module each being arranged in the interior of the solar module with radial spacing therefrom, the solar module having a ventilation opening at both its upper end and its lower end, and the light forming a cover of the lower ventilation opening.

A solar energy harvesting assembly having a unique attachment that can be arranged, mounted, moved and attached to new or existing structures. Solar rings are mounted on any vertical structure that may benefit from solar power using an aesthetically pleasing design that is resistant to wind load. The assembly does not require the need for pitch, azimuth or bearing measurements. The assembly is also capable of energy harvesting from reflected light below with the use of bifacial photovoltaic panels. The mounting design allows the solar energy harvest device to be installed on any vertical structure, including light poles, power poles, parking structures and other minimal load bearing structures. Further, the assembly can be attached to water towers, existing radio towers (guyed, monopole, stealth, self-supporting towers) all used to create vast amounts of unshaded vertical space for solar energy harvesting.

Provided is a lantern comprising: a) a body; b) a speaker attached to the body; c) a light source attached to the body; d) a rechargeable battery to power one or more of the light source or the speaker; and e) a solar panel attached to the body in a configuration that allows light, from outside the body to contact the solar panel to generate electricity to charge the rechargeable battery; wherein the speaker plays sound and the light source provides illumination.

The present invention relates a solar-powered, floating, fountain lamp, comprising a light-emitting elements, a fountain housing, and a solar panel, and the fountain housing acts not only as a three-dimensional lampshade for a first light-emitting portion, but also as a floating portion of the fountain lamp, and the fountain housing is substantially formed by a saucer-shaped cabin and a cylindrical lower part that are integratedly connected to each other, in which the saucer-shaped cabin located in an axially upper part of the fountain housing has an outer peripheral surface that is smooth and curved, and the plurality of light-emitting elements each project a light beam in a different direction, and the light-emitting elements projecting the light beams outward the fountain housing form point light sources at a top of the fountain lamp, the point light sources on the top act as a second light-emitting portion, and the light-emitting elements projecting the light beams inward the fountain housing form the first light-emitting portion, and the first light-emitting portion provides uniform lighting through the three-dimensional lampshade formed by outer walls of the saucer-shaped cabin and of the cylindrical lower part that are smoothly connected.

The present disclosure discloses a transparent lampshade used for solar lamp, comprising a transparent lampshade body, an upper side of the lampshade body is provided with an installing recess for installing a solar luminous lamp assembly, and an upper light-transmitting portion located on a circumference of the installing recess and capable of exposing the solar luminous lamp assembly and transmitting light upwardly. Through cooperation of the installing recess and the upper light-transmitting portion in the disclosure, not only the installation of the solar luminous lamp assembly but also the use effect of light transmission on the upper side can be realized, and the outstanding effect close to the full-lighting even can be achieved, thus to maximally improve lighting effect of the whole solar lamp and bring people a more impressive visual impact, thereby greatly meeting more practical needs and facilitating further innovation and development of industry.

A crosswalk warning light is provided, the crosswalk warning light comprising: a housing which includes a front, the front including a first end and a second end, at least one end including at least one slot, a face with at least one aperture, the aperture defining an outside edge, a step with a riser, the step including or housing at least one optical element, the riser adjacent the outside edge, a top shaped to conform to the front, a bottom shaped to conform to the top, and a back; and at least one bank of light emitting diode (LED) lights positioned such that a portion of the bank of light emitting diodes is aligned with the aperture and a portion of the bank of light emitting diodes is aligned with the step, wherein the at least one optical element is configured to deviate an incident optical path by ninety degrees to provide a deviated optical path that is aligned with the at least one slot.

A solar light stick for use in illuminating and decorating a lawn, garden or pathway. The solar light stick includes a supporting stake, a solar panel, a rechargeable battery, at least one LED, and a tube body. The tube body contains a light transmissive material that may be transparent or translucent. The solar panel charges the rechargeable battery which, in turn, provides power to the LEDs. The LEDs are positioned to provide light to the interior of the tube body. As such, the LEDs may be located within a recess in the tube body. Reflective flakes dispersed within the tube body reflect and disperse light from the LEDs in a decorative manner.
